Coaches can provide an appropriate environment for children to develop a range of movement skills, but there is a dearth of research exploring the creation of appropriate resources to support the coach in developing and assessing children’s Complex Movement Skills. There is also a lack of research around coaches’ perceived feasibility of the limited resources in this area. Therefore, the purpose of this study was to design and then assess the feasibility of a Movement-Oriented Games-Based Assessment (MOGBA) for children aged 8–12 years, to be used by coaches within “Made to Play” programs. Thirteen coaches from across the United States and the United Kingdom used pilot materials to assess the feasibility of MOGBA over a 9-week period. Individual, paired, and focus group interviews were structured and data were thematically analyzed using Bowen et al.’s feasibility framework. Findings suggested that MOGBA provided a welcomed and much needed enhancement to their programs, with effective use of technology-enhanced coaching. Coaching involved notions of pedagogy and assessment, with issues emerging around class size and complexity of assessment. Coaches often used MOGBA covertly and flavored the resource to the sport being delivered, and this revealed to coaches the capability of children not viewed before.
